“…In order to improve the value of the indicator, the method «factory-year» was used, that is, to increase the length of the research period, the indicators of each oil extraction department in the last five years were summarized, the number of observations was n=40. And this satisfies the condition that the number of observations in mathematical-statistical models is 3-4 times more than the number of factors [7].…”

Improving the use of basic funds and production capacity in oil and gas recovery is not only the introduction of new techniques and technology, but also the improvement of labor, management and organization of work. The process of renewal of the fixed capital and production forces is considered intensive at the time when the vast majority of the newly incorporated basic funds and forces are aimed at replacement of morally obsolete and physically worn out parts. This time, their compliance with the economically justified life expectancy is of interest. All these are elements of recycling. Oil and gas wells are important elements of the active part of the main production funds and they determine the future development of oil and gas recovery. Productive use of production wells for oil and gas recovery is considered as a source of improvement of production efficiency in terms of production-resource potential (PRP). In order to increase the efficient use of oil and gas wells as an active element of the main production funds, special attention is paid to both extensive and intensive factors at oil and gas production enterprises.

“…Re-evaluation of total initial extractable reserves (TIRR) of oil and gas bearing regions is performed periodically to obtain a qualitative assessment and establish the profile of reserves across the sedimentary cover section [4,5]. TIRR includes production output and reserves in the discovered fields, as well as localized and non-localized resources within the province (its part) and all OGCs.…”

The geological structure of the Devonian terrigenous complex within the Bashkirian arch located in the well-explored southern part of Perm Krai has been considered in the paper. Due to the limited extent and complex structure of the bulk of reservoir rock in the prospective horizons, these deposits are explored unevenly, usually alongside with the overlying oil and gas bearing complexes. On the basis of the performed analysis of systematic data, the authors justify quantitative parameters for evaluation of non-localized resources after the method of comparative geological analogies in the Devonian terrigenous deposits. The estimated quantity of hydrocarbon resources in the territory under study unequivocally defines it as prospective for exploration and discovery of reserves in the Devonian oil and gas bearing complex. Therefore, the authors have identified areas for priority prospect evaluation survey taking into account the extent of the most promising facies zones of deltaic channels and beach bars.

“…Одним из типичных «старых» районов Волго-Уральской НГП является территория Пермского края, для которой активная разработка нефтяных месторождений ведется с 50 годов 20-го века. Для Пермского края степень разведанности начальных суммарных ресурсов нефти составляет 73%, при явном преобладании в структуре ОИЗ трудноизвлекаемых запасов (83%), активные запасы нефти приурочены в основном к месторождениям с падающей добычей [2]. В противовес этому для большинства каширо-верейских залежей выработка запасов нефти не превышает 20%, в отдельных случаях не достигая 1%.…”

The geological structure of Kashiro-Verey carbonate deposits is considered on the example of one of the deposits of the Perm Region. By combining geophysical studies of wells, standard and tomographic studies of core, the following lithotypes of carbonate rocks were identified: highly porous cavernous, layered heterogeneous porous, heterogeneous fractured porous, dense. It was found that for heterogeneous lithotypes, the porosity estimate in the volume of the permeable part of the rocks significantly exceeds 7%. Experiments on the destruction of rocks were carried out for the selected lithotypes. As a result, it was found that cracks do not form for samples of the cavernous lithotype at a compression pressure of 20 MPa. For a compacted lithotype, already at a compression pressure of more than 10 MPa, an intensive development of fracturing occurs. As a result of multiaxial loading of cores, which can be considered as analogous fracturing of the formation, wide fractures are formed, along which filtration of fluids can occur. Keywords: proppant hydraulic fracturing; X-ray tomography of the core; porosity; permeability; fractured reservoir; oil deposit; carbonate deposits.
